If you sit for a long time and can’t straighten your back, consider that it is related to muscle strain and lumbar spine disease. It can be treated by general treatment, physical therapy, medication, surgery and other methods. 1. General treatment: chronic muscle strain can make the lumbar muscles in a state of tension, spasm. Therefore, it is necessary to develop good sitting and standing postures, which can reduce the pressure on the lumbar spine, and actively exercise the lumbar region, such as small swallow fly, five-point support and other movement exercises, so that the lumbar muscles can relax and improve the curvature of the lumbar spine. 2. Physical therapy: hot compresses, massage, ultra-short wave and other physical therapy can be carried out to promote local blood circulation, relax the muscles and relieve lumbar pain. 3. Medication: non-steroidal anti-inflammatory drugs, such as ibuprofen, diclofenac sodium, etc. can be used to relieve the pain symptoms, but also the application of muscle relaxation drugs, such as epirubicin, chlorzoxazone, etc., is conducive to the relaxation of lumbar muscles. 4. Surgical treatment: If the patient has lumbar spine disease, there are obvious nerve compression symptoms, after conservative treatment is ineffective, can choose surgical treatment, such as minimally invasive intervertebral foramenoscopy surgery. If there is a long time sitting back straight up, it is recommended to go to the hospital for further examination, after the cause of the disease is clear for standardized treatment. The above drugs need to be applied under the guidance of a physician, avoid self-medication.
